摘要
为深入了解T型槽干气密封的端面流场特性,提高其运行稳定性,基于Navier-Stokes方程对端面流场进行了数值模拟。用Solidworks软件建立了T型槽干气密封的三维几何模型,并用Gambit软件对从整体模型中切割下来的计算区域划分网格;采用计算流体力学软件Fluent对端面流场进行了模拟仿真,得到了端面压力场的分布规律。结果表明:T型槽干气密封能产生较好的流体动压效应;使用Fluent软件分析T型槽干气密封性能是可行性的。
Based on the Navier-Stokes equation, the numerical simulation of face flow filed was carried out to obtain more details about the fluid field and high stability of dry gas seal. The three-dimensional geometry model of the T-groove dry gas seal was built in Solidworks software, and the girding of the computing region was reached with Gambit software. The gas flow capacity of T-groove dry gas seal was reached with computer simulation in Fluent software, and the distribution law of T-groove dry gas seal liquid pressure field was gained. The results show that the T-shape groove dry gas seal can produce hydrodynamic pressure, and it is feasible that the sealing performance of the T-shape groove dry gas seal can be obtained by Fluent software.
